When you're jerking off to porn and realize you've seen the video before leading to you remembering the time you blew your load to it.

"What's wrong Neo?"

"I think I jerked it to this porno when I was younger."

"You remember jacking off to it?"

"Yea...what a nostalgia nut."

"Sick dude, let's blow each other again."
